Paraffin Wax
Principal Building Blocks
RX-165, RX-165 Classic, and RX-170 are NSF generic ingredients and listed in the PPI PVC Pipe Range Composition for PVC potable water pipe. These waxes are the building blocks for our lubricant systems. Each of these four products are white in solid state and clear and bright when melted to a liquid.

Paraffin waxes, which are the principal building blocks of most rigid PVC lubrication systems, are simple alkanes with the following basic molecular structure:
Paraffin waxes are alkanes consisting of carbon and hydrogen atoms containing molecules that are both straight (normal) and branched (non-normal).
More than a million different non-normal molecular configurations are possible in a 30+ carbon long molecule. Paraffin waxes 30 to 34 carbons long containing a mixture of normal and non-normal molecules work best in rigid PVC. Lower carbon number paraffin waxes (for example C-26) become soluble in rigid PVC and lose their lubricity at higher processing temperatures. Higher carbon number paraffin waxes (for example C-40) remain insoluble and can be difficult to fuse. Waxes of similar carbon numbers containing different molecular structures can perform very differently and unpredictably in rigid PVC.
Performance consistency of paraffin waxes in rigid PVC is defined by the molecules present. Rheogistics manages the molecular consistency of its lubricants by consuming steady streams of reliable feedstocks directly from major wax producers and carefully managing product compositions.
